ANALOG DEVICES EVAL-LTC7891-AZ Evaluation Board, LTC7891RUFDM#PBF, Synchronous Step Down Controller, Power Management

EVAL-LTC7891-AZ is an evaluation circuit featuring the LTC®7891: a 100V step-down synchronous GaN FET controller. The LTC7891 is specifically designed to drive up to 100V GaN FETs safely and easily through internally optimized bootstrap switches and smart dead time control. Split gate drivers allow for easily adjustable turn-on and turn-off of FETs. Additionally, the IC features low IQ, up to 3MHz programmable/synchronizable switching frequency, spread spectrum, and a small 28-lead (4mm x 5mm) side wettable QFN package. These features allow for a wide variety of applications including industrial, military, medical, and telecommunications systems. The EVAL-LTC7891-AZ provides a high-performance cost-effective solution for generating a 12V output.

• Input voltage range from 15 to 72V at IOUT = 0A to 20A, heatsink
• 12V typ output voltage at VIN = 15V to 72V
• 500KHz typ switching frequency at JP2 = Disable SS (SSFM Off)
• 98% typical efficiency at IN = 24V, IOUT = 20A
